Bile duct obstruction is a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine. In serious cases, the common bile duct can be surgically moved so that it empties further down the small intestine.
1 A bowel obstruction is a blockage of the small or large intestine by something other than fecal impaction.  The most common cancers that cause bowel obstructions are cancers of the colon, stomach, and ovary. Other cancers, such as lung and breast cancers and melanoma, can spread to the abdomen and cause bowel obstruction. Patients who have had surgery on the abdomen or radiation therapy to the abdomen have a higher risk of a bowel obstruction. Bowel obstructions are most common during the advanced stages of cancer.
